I was looking at some of the pics and it looks like the GTHaus does not retain the factory valves.

I have a GTHaus on my 2015 Grand Cherokee SRT and it sounds insane with the valves open.

Might be a dumb question but, if both Eisenmann Valved and Race have valves why would someone go with the valved system over the race (as it's 1k more)? Is the race just louder? Does it have to do with back pressure and performance? Seems like the race is lighter too.
The Race is not valved. It only has provision to hold the valve controllers so the wires are still plugged in.

Gotcha. Thanks for the response. I've heard a few videos of the race exhaust in comfort mode (from a friend who installed it and youtube clips) and it is significantly quieter than in sport/sport plus mode. I always thought this had to do with valve control but maybe it's the tuning?

I'm probably going to still go with the race axleback as it doesn't seem too crazy loud unless you also get the midpipe. Besides valves, are there any other differences performance wise?

I have been through this... they all appear full system , or some cutting required...

Looking for bolt on / slip on back box only - for better sound (like the MPE backbox...)

Thanks

Only bolt-on is impossible and does not exist.

The stock system is a full system that goes from front to back without having a cut point or connection point for the pipes.

EVERY slip-on or backbox requires cutting! There is no way around that other than buying a full system from downpipes till the back.

Make your choice based on the list I shared.

Please share an audio clip! That's exactly what I want to do with a vrsf DP. You actually maybe the first to have Eissemann/AA mid setup.

I think people are concerned that itís more restrictive than the other options. The pipes are definitely smaller, 3 inches I believe instead of most 3.5.

Havenít heard it in person, but sounded good from the clips Iíve heard.
